and
§ D Board Diagrams
.
The location of the console connector and of the keyboard and mouse connectors depends of the configuration
of the USPIIi-1v.
2.5.1
Console Port (TTYA)
In PS/2 mode: attach one end of cable 108113 to the front panel “Console” connector and the other end to a
ASCII serial terminal or emulator
In Sun mode: attach one end of cable 108376 to the front panel “TTYC” connector and the other end to a
ASCII serial terminal or emulator.
Note —
USPII-1v serial ports are wired in “DCE” mode. A null modem and a gender-changer may be
required for attachment to your serial terminal or emulator
Note —
If the USPIIi-1v is used with Creator Graphics, it is not mandatory to attach it to a serial terminal if
already connected to PS/2 or Sun keyboard/mouse. In this case, software will automatically use this keyboard
for input and the Graphics port for output.
